SEEDLING TRANSPLANTER

To provide a seedling transplanter in which left and right seedling sandwiching planting claws properly plant a seedling in order to solve such a problem that planting of the seedlings is not properly performed in a case where the opening degree of the left and right seedling sandwiching planting claws is not sufficient and the opening timings dot not match with each other even though the left and right seedling sandwiching planting claws plant the seedlings in the ground by being opened at prescribed timing.SOLUTION: There is provided an extrusion rod 55 equipped with an extrusion part 56 which extrudes a seedling sandwiched by left and right seedling sandwiching planting claws 31 into the ground, an extrusion actuation mechanism 35 of the extrusion rod 55 is constituted by an extrusion cam 41b and two extrusion rod arms 58a, 58b whose ends are pivotally connected to each other, an extrusion follower part 59 which is brought into contact with the extrusion cam 41b is provided in one extrusion rod arm 58a and a base part is pivotally supported by a frame 36a of a seedling planting device 6, the other end of the other extrusion rod arm 58b is connected to the base part of the extrusion rod 55, and there is provided a spring which biases the two extrusion rod arms 58a, 58b in the closing direction.SELECTED DRAWING: Figure 4 【課題】左右苗挟持植付爪は、所定のタイミングで開いて苗を土中に植付けるが、左右苗挟持植付爪の開度が十分でなかったり、開放するタイミングが合っていない場合、苗の植付が適切に行われない。そこで、左右苗挟持植付爪が適正に苗を植付ける苗移植機を提供する。【解決手段】左右苗挟持植付爪３１が挟持した苗を土中に押し出す押出部５６を装備した押出ロッド５５を設け、押出ロッド５５の押出作動機構３５を押出カム４１ｂと互いの端部を枢支連結した２つの押出ロッドアーム５８ａ，５８ｂにて構成し、一方の押出ロッドアーム５８ａに押出カム４１ｂに接当する押出従動部５９を設けて基部を苗植付け装置６のフレーム３６ａに枢支し、他方の押出ロッドアーム５８ｂ他端部を押出ロッド５５基部に連結し、２つの押出ロッドアーム５８ａ，５８ｂを閉じる方向に付勢するスプリングを設ける。【選択図】図４
